Abstract

The octupole bands in the Z∼88, N∼134 region, with their abundance of experimental information, offer a real challenge for different nuclear structure models. In this region, quasimolecular bands, which are thought to indicate the presence of stable octupole deformation, have been observed. The quantities most often reported are the B(E1)/B(E2) branching ratios from these levels. The calculations in the framework of the spdf model show that the 1-pf boson limit (dipole-octupole vibrations) can describe the essential experimental features related to the octupole bands in the Rn-Th region.
